The topic for this article is how read the text of a PDF document, export into txt file, and return the results as text or string.

This is code for adobe reader X Version 10.1.3, so if the next time you get some code that doesn't run as well might be due to different versions.

This article will explain clearly how we can make simple PDF Automation. If you can't understanding  the code, I have set up the source code so you can debug the code and you can download it from here.

Let's start the code :

This is the image information from the PDF

        //change it if you have different pdf version 10.1.3
        string strAcrobatReaderType = "AcroRd32";        string strDir = Application.ExecutablePath.Substring(0,      Application.ExecutablePath.LastIndexOf("\\bin") + 1) + "files\\sample.pdf";
        ProcessStartInfo pInfo = new ProcessStartInfo(@"C:\Program Files\Adobe\Reader 10.0\Reader\" + strAcrobatReaderType + ".exe", strDir);
        Process.Start(pInfo);

       //wait the window is opened
       autoit.WinWaitActive("[CLASS:AcrobatSDIWindow]", "", 50);
       if (autoit.WinExists("[CLASS:AcrobatSDIWindow]", "") == 0)
       {
                MessageBox.Show("Windows didn't open");
        }

       //save as text document
       //send keys ALT + f + a
       autoit.Send("!fax", 0);

      int iCountRentry = 0;
     
      //Wait Save As Window is open and check if don't open
      autoit.WinWaitActive(strSaveAsTitle, "", 1000);
      if (autoit.WinExists(strSaveAsTitle, "") == 0)
      {
                MessageBox.Show("Save As Windows didn't open");
       }

       //send keys file directory to save
       do
       {
                if (autoit.ControlGetText(strSaveAsTitle, "", "Edit1").Equals(strDir))
                break;

                //send CTRL + a
                Type("^a", 0, "Edit1", true, 1000, strSaveAsTitle);
                Type(strDir, 0, "Edit1", true, 1000, strSaveAsTitle);

                iCountRentry++;
        }
        while (iCountRentry < 10);
        if (iCountRentry > 10)
        {
                MessageBox.Show("Error sending keys file directory");
        }

Click Save Button Image

        //or using send key ENTER
        //Type("{ENTER}", 0, "Button2", false, 1000, strSaveAsTitle);

        //read text
        iCountRentry = 0;
        do
        {
                try
                {
                        using (StreamReader reader = new StreamReader(strDir))
                        {
                                 resultTextBox.Text = reader.ReadToEnd();
                        }
                        break;
                 }
                 catch
                
                        Application.DoEvents();
                        Thread.Sleep(1000);
                        iCountRentry++;
                 }
           } while (iCountRentry < 10);
}

Notes :
If this project  didn't working, you have to change some code such as Title, Control, Control Click X and Y. Autoit working because of the screen according to the PC you are using.
Using function of autoit control is better than the others because it is more accurate if used on another PC.

If you getting problems about this please leave a note in the comments so I can help you.

You can adding this code into your project. This is additional function that I have made, you can copy and paste.

private void Type(string strKeys, int nMode, string strControl, bool blnSleepKeys, int nSleep, string strWindow)
        {
            if (blnSleepKeys)
            {
                char[] achKeys = strKeys.ToCharArray();

                foreach (char ch in achKeys)
                {
                    autoit.ControlSend(strWindow, "", strControl, ch.ToString(), nMode);
                    Thread.Sleep(100);
                    Trace.WriteLine("Sent Key: '" + ch.ToString() + "'");
                }
            }
            else
            {
                autoit.ControlSend(strWindow, "", strControl, strKeys, nMode);
                Trace.WriteLine("Sent Keys: " + strKeys);
            }

            for (int i = 0; i < (nSleep / 100); i++)
            {
                Application.DoEvents();
                Thread.Sleep(100);
            }
        }

        private void Click(string strButton, int nNumClicks, int nX, int nY, string strControl, int nSleep, string strWindow)
        {
            autoit.ControlClick(strWindow, "", strControl, strButton, nNumClicks, nX, nY);

            for (int i = 0; i < (nSleep / 100); i++)
            {
                Application.DoEvents();
                Thread.Sleep(100);
            }
        }
